    <p>I render a picture in local using html5 and File API.</p> <p><strong>html:</strong> </p> <pre><code>&lt;form action="/Picture/UpdateProfilePicture" id="profile_pic_form" method="post"&gt; &lt;input type="file" id="file"&gt;&lt;br&gt; &lt;/form&gt; &lt;div&gt; &lt;output id="result"&gt;&lt;/output&gt; &lt;/div&gt; </code></pre> <p><strong>javascript:</strong> </p> <pre><code>&lt;script type="text/javascript"&gt; function handleFileSelect(evt) { var files = evt.target.files; var file = files[0]; if (files[0].type.match('image.*')) { var reader = new FileReader(); reader.onload = (function (theFile) { return function (e) { // Render thumbnail. var span = document.createElement('span'); span.innerHTML = ['&lt;img id="cropbox" class="thumb" src="', e.target.result, '" title="', escape(theFile.name), '"/&gt;'].join(''); document.getElementById('result').innerHTML = ""; document.getElementById('result').insertBefore(span, null); }; })(file); // Read in the image file as a data URL. reader.readAsDataURL(file); //$('#cropbox').Jcrop(options, function () { jcrop_api = this; }); } else { alert("the file you entered is not a picture"); $("#profile_pic_form").each(function() { this.reset(); }); } } $(document).ready(function() { // Check for the various File API support. if (window.File &amp;&amp; window.FileReader &amp;&amp; window.FileList &amp;&amp; window.Blob) { document.getElementById('file').addEventListener('change', handleFileSelect, false); } else { alert('The File APIs are not fully supported in this browser.'); } }); </code></pre> <p></p> <p>The js gets the file and generate the span &amp; img tag inside the output tag.</p> <p>What I want now is to "Jcrop" the picture BUT when I try <em>$("#cropbox).Jcrop();</em> nothing happens, why ? </p>

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.

If you are curious you may find further information in the browser console, which is accessible through the devtools (F12).
